Title: Plasma etching equipment
Inventor: SADOHARA TAKESHI
IPC: C23F4/00
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To effectively prevent corrosion of the inside of a vacuum vessel, by adsorbing neutral active species which spread in the vacuum vessel and do not contribute to etching by a reacting member arranged in the vacuum vessel, and making reaction product leave the reacting member by reaction with the reacting member. SOLUTION: A reacting member 6 is arranged on a substrate holder 30. Before neutral active species of fluorine reach the inner wall surface of a vacuum vessel 1, the neutral active species of fluorine which do not contribute to etching are adsorbed by the reacting member 6. Since the reacting members 6 are arranged on the inner wall of the vacuum vessel 1 and covers 34, 37, the neutral active species of fluorine are adsorbed also by these reacting members 6. As a result the inner wall or the like of the vacuum vessel 1 is hardly corroded as compared with a conventional one. Since the neutral active species of fluorine which are to invade the back of a semiconductor wafer 50 are adsorbed by the reacting member 6 arranged on the substrate holder 30, the edge part of the semiconductor wafer 50 is not deeply etched as compared with a conventional one.

Title: Driving circuit for stepping motor
Inventor: ITO SHUNICHI
IPC: H02P8/12
Filed: 1989-08-17
Abstract: PURPOSE:To reduce the copper loss of a phase winding by half by setting the absorption voltage of a counter-electromotive force absorbing circuit to be low voltage till counter-electromotive current flowing at the time of switching the phase winding is reduced into almost zero. CONSTITUTION:When start signal is applied, then from an over-drive signal generator 3 and a pulse train generator 1, output is generated and working is started. By the output of a distributing circuit 2, transistors TR1, TR2 are turned ON/OFF, and current is fed to phase windings L1, L2. When the transistor TR1 is turned OFF, then electromagnetic energy stored in the phase winding L1 is regenerated to a power source E1 via a diode D2, the phase windings L2, L1, a diode D3, and the transistor TR5 of a counter-electromotive force absorbing circuit 10. In this case, the transistor TR6 of an absorption voltage switching circuit 11 is turned ON, and the transistor TR5 is also ON, and so a loss is less at the transistor TR5. Besides, counter-electromotive current is to be of 1/2 of the conventional one, and so a copper loss is reduced.

Title: Printer
Inventor: KATSURA AKIRA
IPC: B41J2/24
Filed: 1989-08-16
Abstract: PURPOSE:To set a specific printing start position by a method wherein a shutter for opening and closing a detection hole in a detection plate is provided to a signal generator generating a printing dot timing signal, a means which moves compulsorily the shutter is also provided, and output of the dot timing signal is interrupted or passed by means of the shutter. CONSTITUTION:A light emitting element 26 and a light receiving element 27 attached to a holder 21 are arranged above and below a plurality of detection holes 25 arranged at equal intervals on a concentric circle of a detection plate gear 20. When the detection hole 25 passes through its optical axis, a signal is emitted from the light receiving element 27. Since rotation of the detection plate gear 20 is mechanically synchronized with sliding of a printing head 5, even though rotary speed of a DC motor 17 varies, the dot interval never varies. Further, a shutter 23 is supported rotatably around a shaft 24. When a slide block 7 moves to the right, one end of the shutter 23 is pushed, and the other end of the shutter 23 intercepts the optical axis. When the slide block starts to move to the left, the shutter is returned to an original state by a torsion spring 22, and the signal starts to be emitted from the light receiving element 27.

Title: Power device
Inventor: SAKATA KATSUMI
IPC: H02M7/12
Filed: 1992-08-07
Abstract: PURPOSE:To prevent rush current by a simple structure and to prevent re-rush current at the time of an instant stoppage of power, in a power device. CONSTITUTION:When turning on a commercial AC power supply 1, a switching element 8 is turned ON. Since a smoothing capacitor 3 having no storage of electric charge is nearly in a shorted condition, a large current tends to flow in a shunt resistor 5. However, when the current reaches a certain level, a light emitting diode 7a of a photo coupler 7 conducts and then a photo transistor 7b conducts and turns the switching element 8 OFF and thereby charging of the smoothing capacitor 3 is stopped. By repeating this operation, the smoothing capacitor 3 is charged little by little, with a peak of rush current being controlled. The current just after rectification is detected at real time and the charging current of the smoothing capacitor is controlled, so rush current can be prevented in a simple circuit configuration.

Title: Facsimile equipment
Inventor: SHOJI SHINICHI
IPC: H04N1/40
Filed: 1988-08-24
Abstract: PURPOSE:To improve transmission efficiency by outputting specific inaccurate compressed data having a dot length shorter than a normal dot length and satisfactory compressibility to a facsimile network when data for each line continue with similarity equal to similarity set from an external part according to the type of an original or above. CONSTITUTION:When the similarity becomes equal to the similarity set from the external part correspondingly to the type of the original or above, a similar line signal is outputted. The specific inaccurate compressed data having the short dot length and high compressibility are previously stored in an inaccurate data buffer 7, and the inaccurate data buffer 7 receives the similar line signal and supplies the inaccurate compressed data to an output circuit 6. When the inaccurate compressed data are inputted from the inaccurate data buffer 7 to the output circuit 6, the output circuits 6 refuses compressed data from a compressor 3 and outputs the inaccurate compressed data from the inaccurate data buffer 7 to a facsimile network instead of the refused compressed data. Thus, it can be eliminated that a large quantity of data are outputted to the facsimile network even when similar image lines continue.

Title: Electronic cooking range
Inventor: HIRATA KENGO
IPC: H05B6/68
Filed: 1992-08-07
Abstract: PURPOSE:To stop a turn table upon start of a cooking irrespective of the length of a cooking time by detecting the cooking start position of the turn table in accordance with a timing when a roller passes a weight sensor and stopping the turn table at the cooking start position after the cooking is finished. CONSTITUTION:Time from the start of a cooking to a roller 36 first passing through a weight sensor 37, that is, time DELTAT required for obtaining a prescribed electromotive force waveform is stored. Time required from the generation of the first electromotive force waveform to that of a next electromotive force waveform, that is, 1/3 of a rotating time T is also stored. Then, when a cooking time becomes zero, a turn table 35 is stopped when the turn table 35 further rotates for time (T-DELTAT) after the number of generations of electromotive force becomes the multiple of 3. Thus, the turn table can be stopped at the same position as that upon the start of the cooking after the cooking is finished, irrespective of the length of the cooking time.

Title: Picture display device
Inventor: YOSHIDA TOSHIFUMI
IPC: H04N5/66
Filed: 1984-10-09
Abstract: PURPOSE:To keep a stabilized electron beam emitting capacity for a long period by detecting the reduction in electron beam emitting amount from a line cathode due to aging and controlling a line cathode drive circuit so that temperature of the line cathode can be increased when the electron beam emitting amount is reduced. CONSTITUTION:Corresponding to line cathodes 2a-2o an electron beam emitting amount detection circuit 45 detects an electron beam emitting amount through a resistance 44, and supplies the difference from its reference to memory circuits 46a-46o for storing line cathode heat voltages of line cathode drive circuits 26a-26o. As a result the electron beam emitting amounts of the line cathodes 2a-2o come to reference values and are stabilized. In order to reduce the picture quality deterioration due to the dispersion of the partial electron beam emitting amount in one line cathode, which comes to the brightness irregularity on a screen, the temperature of the line cathodes 2a-2o is set so that they can have the higher electron beam emitting capacity than that under actual using conditions, and the sufficient electron beam supply capacity is given to the line cathodes 2a-2o. Consequently the dispersion of the electron beam emitting capacity of each line cathode is masked due to the influence of a space electric charge, the dispersion of brightness can be substantially improved.
